When you open a modal bottom sheet in iOS, the previous background (the page before open the modal) has an animation, it goes thinner and seems the page and the modal build a stack of pages.
I know how to open a modal bottom sheet in flutter, but I don't know how to animate the previous page like native iOS does. I used to use this package: https://pub.dev/packages/modal_bottom_sheet (in particular I use the first example: Cupertino modal). I'd like to achieve the same animation without use any package.
old question: I'm trying to achieve this effect for the modal bottom sheet like native iOS does (I refer to the page under the modal) I used to use a package but this time I'd like to do it without any installation. Do you know if it is possible?
go to github, go to examples, and find this code in the main file:
showCupertinoModalBottomSheet( expand: true, context: context, backgroundColor: Colors.transparent, builder: (context) => ModalFit(), ))
You also need to make sure your parent screen is gonna be kept alive.
